Location tracking system

A position tracking system is provided to process position information of a moving device by periodically transmitting data generated in an inner part or data generated from an external device to a position measurement server. A moving device(100) includes a position information receiving part(110), a frequency transceiving device(120), an additional data transceiving part(130), and a power part(140). The position information receiving part collects GPS position information. The frequency transceiving device transmits/receives a low frequency like radio frequency and a wireless LAN high frequency like IEEE 802.11. The additional data transceiving part communicates with an information collection device about an external environment like position data, temperature, and humidity. The power part is semi-permanently used.
